Work Experience

2019 - PRESENT


  • Founded with a team of four a fintech startup that offered a SaaS and a business model made up of a B2B and B2C. The B2B part allowed all the banks and the fintech to coexist in a common space and the B2C brought customers to this space.
  • Oversaw and created the architecture of the app and thought about how the microservices are going to interact with each other. Transitioned eventually to the front-end part because there was a need at the time.
  • Worked in a hectic environment, built a very exciting product, and showcased it to some strong players in the fintech world. One of which is the director of Banca Transilvania and the one from Banca Feroviara Romana.
  • Built a company that had the principal value proposition of putting all the banks and financial institutions on common ground (by implementing APIs from the banks that accepted European open banking regulations) thus building a free fintech market.

P4 Deep Learning Detection of Network Intrusions

I developed a system that detects intrusion on the network using low-power programable switches and machine learning algorithms by leveraging both the detection done by a neural network and also the speed of the Tofino switch.

I am now studying the impact of Markov chains in network anomaly detection.

Zoom Clone

I created this application for a workshop that I have kept for Ivy Hacks (a hackathon for people from Ivy League universities). It is a simple camera (Zoom) clone for a full-stack pancakes (client, server) workshop.

App Features:
• You can connect to a server
• You can video chat with others in a single room
• You can have multiple rooms and let the people connect to them

Signature Forgery Detection Tool

I created a signature analyzing tool using JavaScript and HTML5. It detects forgeries by analyzing the way that your hand moves when you are signing. The scope of this project was to help prevent fraud and falsification signatures for bank statements.

Presentation Application for the National Botanical Garden

With this app, you can recognize plants with a phone camera, do a guided tour, see events all within one mobile application with connection to the Azure cloud platform.

The project was the MVP for the National Botanical Garden in Bucharest and the project continues right now using the code that I and my team have written for it.

ECMWF IFS Python Bindings

This showcases how a modern, interactive, development environment can enhance scientific productivity for ECMWF’s Integrated Forecasting System (IFS) by calling individual Fortran routines from a Jupyter notebook.

Tools and Examples for Visualizing HPC Performance Data for the IFS

I created an interactive way of displaying HPC metrics for the IFS using interactive metrics plotting techniques. I also improved both the reporting capabilities of the IFS developer and the efficiency in finding performance bottlenecks by the IFS developers.
